TROUBLESHOOTING YOUR HYDROSEEDER®
Because of the tremendous work load usually placed upon the HydroSeeder
®
, minor malfunctions will
occur from time to time. If these are not remedied immediately, they could lead to poor performance
and damage to the equipment. This section describes symptoms, possible causes, and the corrective
action(s) to take.
1. Foam in the tank and air entrainment:
The mixture of dry materials with water will sometimes cause excessive foaming, while other
dry materials with water mixtures will cause air entrainment. These situations will reveal them-
selves with the occurences of an erratic slurry discharge, a drop in the pressure of the dis-
charge, and a drop-off in distance of slurry discharge.
Some solutions are:
A. As slurry level drops in the tank, slow the agitator.
B. Add 2 to 3 oz (6 to 9 cl) of an antifoaming agent to tank.
C. If you can determine which additive is causing the air problem, either add it last or not at
all – unless it’s the water.
D. Limit recirculation time as much as possible.
2. Plugging or clogging:
DANGER
Turn off engine and disconnect battery cables before working on equipment. Failure to comply
will result in death or serious injury
Sometimes, when a stoppage occurs, you will not be able to find anything in the line. When this
happens, it means that the system became airbound instead of plugged. To remedy this, see
FOAMING OF SOLUTION AND LACK OF DISTANCE on pages 30 and 31. Plugging can occur
in any one of four places: the valve and recirculation nozzle, the discharge nozzle, the pump
area, and the sump area. The plugging is caused by either foreign objects or dewatered mulch.
A. Obstruction in the discharge nozzle is determined by a change in or stoppage of the spray pat-
tern.
1. Disengage (turn off) clutch.
2. Make certain that pump has stopped rotating.
3. Slowly and carefully remove nozzle.
4. Using the nozzle cleaning rod attached to the underside of the guard rail, clear the
nozzle.
DANGER
Severe injury can result from opening clamps when piping is hot. Before loosening any clamps,
determine if the pipe is hot. If so, let it cool before attempting repair. Failure to comply will
result in death or serious injury.
